Specification of Letters Patent.

Patented Feb. '22, 1921.

Application filed January 27, 1919.; Serial No. 273,322.

of the casing and opening directly intoa' fire pot below it, may be readily cleaned through a door at the front of the combustion chamber.

Another object of the invention is to provide, in combination with the above-mentioned features, a series of deflector plates in the combustion chamber which cause the heated products of combustion to take a zigzag course through said chamber but which may be moved to a osition so as not to interferewith the cleaning of the chamber through the door. at the front thereof.

. The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: l s

Figure 1 is a vertical sectional View through the furnace embodying the inven tion' F fg. 2 is a section taken on the line 22 of Fig. 1;

Fig. 8 is a detail view of one side of the furnace;

Fig. i is a detail sectional view through one of the damper journals.

In the drawings the numeral 5 designates the outer casing of the furnace, 6 the ash pit, 7 the fire pot mounted upon the ash pit and carrying a grate .8, and 9 the combustion chamber extending from the front wall 10 to within a short distance of the rear end of the furnace and being spaced a relatively short distance from the sides, top and rear of the casing 5. p

A hinged door 11 on the front wall 10 provides access to the ash pit 6 and a hinged door 12 in said wall provides access to the space in front of the fire pot in which a water pot 13 is supported upon a portion of the top of the ash pit.

The combustion chamber 9 is preferably long rectangular shaped combustion ,cham-, ber secured at its front end to the wall 10 and rendered accessible from the outside by a hinged door 14 on said wall. The rear end 15 of the box like combustion chamber .9 is preferably spaced from the rear end 16 "of STATESPATENT OFFICE.

the outer casing and an outlet pipe 17 leads from said end through the casing and has an extension 18 provided with a hinged check damper 19' of usual construction. The com bustion chamber9 has a circular opening 20 adjacent its front end communicating with the top ofthe fire pot 7 and a fiangedring 21 surrounds saidopening' and rests upon the upper end of said flared fire pot to support the front end of said combustion chamber and an angled strip 22 supports therear end of said combustion chamber. Withthis construction the soot may be readilykremoved from the walls of the combustion chamber 9 and scraped orbrushed into the fire pot by the use of proper tools inserted into said combustion chamber through the opening .in the front wall.

Outlet pipes 23 lead from the top of the casing 5 to the rooms'to be heatedand the upper portion of saidcasing is reinforced and stiffened by angled strips 24friveted thereto. In orderto direct the heated products of combustion against the side, walls of the combustion chamber and to retard their 'passage when desired, a series of deflector plates 25, 26, 27 and 28 aredisposed in'said combustion chamber between the opening 20 and therear endof said chamber. i

. The .plate 25 ismounted on a rod 29 provided with'acrank 30 and is spaced at its ends a hort distance from the sides of the combustion chamber 9. The plates 26 and 27 are mounted upon a rod 31 provided with a crank 32 and are spaced apart at the central portion of the rod..

The plate 28 is mounted on a rod 33 provided with a crank 34 and. is spaced at its ends a short distance from the sides of the combustion chamber 9.

Each of the rods 29, 31 and 33 are journaled in pipe sections 35 having threaded ends '36 receiving nuts 37 to clamp said sections to the combustion chamber 9 and cas- 1 The cranks 30, 32 and Sat are pivotally connected at their free ends to a common actuating bar 40 carrying a weight 41 to normally maintain the plates in vertical position by means of a flexible connection such as chain 42.

WVith this construction the products of combustion may be made to flow in the zigzag path shown in Figs. 1 and 2 so as to deflect them against the sides, top and bottom of the walls of the combustion chamber.

-The cold air is fed to the furnace through a pipe 43 centrally located in one side of the casing 5 adjacent the bottom.

In starting the furnace the deflector plates are moved to horizontal position to allow for a good draft and later are inclined with respect to the horizontal to re tard the flow of the products of combustion toa greater or less extent. The cold 7 air entering the bottom of the furnace flows around the fire pot 7 and around the combustion chamber 9 passing up the sides and rear end of said combustion chamber and thence over the top and out through the pipes 23.

WVhen the deflector plates are disposed in horizontal position it is a simple matter to scrapeor remove the soot from the walls of the combustion chamber and deposit it in the fire pot 7.

From the foregoing description it will be noted that the furnaceis of simple construction, may be easily cleaned, and efficiently heats the air used for heating purposes.

What I claim as new and desire to secure by Letters Patent is:

1. In a hot air furnace, the combination, with an outer casing, of a rectangular combustion chamber of less height than width and mounted within the casing and spaced.

a short distance from the'sides, top and rear walls of the casing, a door at the front of the casing for direct access tothe front end of the combustion chamber, said combustion chamber having an opening in its bottom near the door, a fire pot disposed below and having its top communicating directly with said opening, a portion of the combustion chamber extending rearwardly from the fire pot, and an air inlet to the casing beneath this rearwardly extending portion.

2. In a hot air furnace, the combination, with an outer casing of a horizontally disposed rectangular combustion chamber of less height than width and mounted within the casing at the upper portion thereof, a door at the front of the casing for direct access to the front end of the combustion chamber, said combustion chamber having an opening in its bottom near the door, a fire pot disposed below and having its top communicating directly with said opening, a portion ofthe combustion chamber extending rearwardly from the fire pot, a series'of rectangular deflector plates within the rear portion of said-chamber and pivotally supported in'the sides thereof, some of said plates having their ends spaced from the sides of said chamber and a pair of intermediate plates with their outer ends close to the walls of said chamber and their adjacent inner ends spaced from each other to direct the products of combustion into, contact with. the walls of said chamber, means for moving the plates in the same direction, the movement of said plates to open position permitting ready cleaning of the combustion chamber from the door, means for conducting cold air to the casing beneath the rearwardly extending portion of the combustion chamber, and means for conducting the heated air from the upper portion of the casing.

In testimony whereof, I affix my signature, in presence of two witnesses.
